Re: variable declaration question

in reply to variable declaration question

To add to what tobyink said, "none" - in context.

my $foo = @some_array_value and my ($foo) = @some_array_value will give two very different results.

print(my $foo = (1, 2, 3), "\n");
print(my ($foo) = (1, 2, 3), "\n");
__END__

Update: Alright, either QuickDraw McGraw updated his node, or I skipped over the second and following line when I read it. :-) We stated basically the same thing.

[tobyink]

I updated. It was an afterthought as it didn't seem relevant to the question. (The question included semicolons after the declaration, so the variable is not being initialized.)

print(my $foo = (1, 2, 3), "\n");
print(my ($foo) = (1, 2, 3), "\n");

Ah, I see. The line:

print(my $foo = (1, 2, 3), "\n");

is a convenient way of assigning the last element of an array to a variable.

Try:
print(my $foo = ('a', 'b', 'c'), "\n");
vs:
my @foo = ('a', 'b', 'c'); my $bar = @foo; print $bar, "\n";
I like using letters vs numbers to avoid confusion...

Quite right. ++
